A black hairy tongue is caused by too much bacteria or yeast growth in the mouth: the bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections.
The causes of black, hairy tongue include poor oral hygiene and excessive use of medications containing bismuth, such as Pepto-Bismol. Other causes include antibiotic use, which can change the normal bacteria content in the mouth. Heavy tobacco use is also a cause.
